VTS Safety & Emergency Response Operations 4 — Questions and Answers
Question 1: What is the VTS operator's role during a Vessel Security Alert System (VSAS) activation?
- Immediately broadcast the vessel's position on Channel 16
- Notify maritime security authorities and avoid broadcasting the alert publicly (Correct answer)
- Direct all vessels in the area to maintain a 500-meter exclusion zone
- Contact the vessel's owner to verify the alert is genuine
Correct answer: Notify maritime security authorities and avoid broadcasting the alert publicly
A VSAS activation is a covert security alert; VTS operators notify maritime security authorities discreetly and must not broadcast the alert, which could endanger the crew.
Question 2: A tug operator reports a tow line has parted and the barge is drifting toward a bridge. The VTS operator's IMMEDIATE priority is:
- Contact the bridge authority to prepare for impact
- Warn other vessels in the area and coordinate emergency response resources (Correct answer)
- Order the tug to re-establish a tow line before taking other action
- File an incident report with the COTP
Correct answer: Warn other vessels in the area and coordinate emergency response resources
Immediate broadcasting of the hazard and coordinating response protects other vessels and allows emergency resources such as salvage tugs to respond before impact.
Question 3: Under the National Search and Rescue Plan, who has primary federal responsibility for maritime SAR in U.S. coastal and inland waters?
- Federal Emergency Management Agency (FEMA)
- Department of Defense (Navy)
- United States Coast Guard (Correct answer)
- National Oceanic and Atmospheric Administration (NOAA)
Correct answer: United States Coast Guard
The U.S. Coast Guard has primary federal responsibility for maritime SAR operations in U.S. coastal and inland waters under the National Search and Rescue Plan.
Question 4: A vessel master advises VTS that his vessel has a medical emergency and requests priority vessel traffic service. The correct VTS response includes:
- Denying the request as medical emergencies are not a VTS function
- Issuing a PAN-PAN medical broadcast and coordinating expedited vessel movement (Correct answer)
- Transferring all communications to the Coast Guard and ceasing involvement
- Contacting the nearest hospital for medical advice
Correct answer: Issuing a PAN-PAN medical broadcast and coordinating expedited vessel movement
VTS supports medical emergencies by broadcasting a PAN-PAN medical urgency signal and expediting the vessel's movement through traffic to reach medical assistance quickly.
Question 5: When a vessel reports an oil spill in your VTS area, which federal law governs the mandatory reporting requirements?
- Ports and Waterways Safety Act (PWSA)
- Oil Pollution Act of 1990 (OPA 90) (Correct answer)
- Clean Water Act Section 311
- Jones Act
Correct answer: Oil Pollution Act of 1990 (OPA 90)
OPA 90 (Oil Pollution Act of 1990) establishes mandatory reporting, response, and liability requirements for oil spills in U.S. navigable waters.
Question 6: A VTS operator notices on radar that two vessels are on a collision course but neither has reported the situation. The operator should:
- Wait until the vessels recognize the situation themselves
- Contact both vessels, provide traffic information, and issue a navigational recommendation (Correct answer)
- Only contact the vessel that appears to have the right of way
- Alert the harbor pilot and take no further action
Correct answer: Contact both vessels, provide traffic information, and issue a navigational recommendation
VTS operators have a proactive duty to provide traffic information and navigational recommendations to prevent collisions, even if vessels have not reported the situation themselves.
Question 7: Which of the following scenarios would trigger a MAYDAY broadcast rather than a PAN-PAN broadcast by the VTS?
- A vessel with a medical patient needing shore-based physician consultation
- A vessel taking on water with crew preparing to abandon ship (Correct answer)
- A vessel with a fouled propeller drifting in a shipping lane
- A vessel reporting a minor fire contained to the galley
Correct answer: A vessel taking on water with crew preparing to abandon ship
A vessel in grave and imminent danger requiring immediate assistance, such as sinking with crew abandoning ship, warrants a MAYDAY — the highest level of distress.
